Curvature in mathematics is the rate of direction and is the amount by which the geometric surface itself derives from being a straight line. A fiber bundle is a localized as a multiplication space, but which as have a different topological structure as a whole. In differential geometry the curvature form describes curvature of a connection on a principal bundle. Our goal in this paper is to identify the concept of curvature in fiber bundles, we followed the analytical historical mathematical method and we found that curvature is a scalar quantity that can be determined and most material things are curvature or midwife curvature.
